I would take another crack at your Trifield settings. I can't speak to the quality of your PC source for stereo through the USB connection, but let's just assume for the sake of argument that it's on par with a ID40 or ID41. The Trifield treatment should be really good. You should get a good front soundstage with light fill from the back.

However, it's not necessarily fair to compare Trifield to a multichannel mix off of a SACD or DVD-A. Some mixes are good and some are not. There are some DVD-A mixes that use the ".1" channel for something other than the subwoofer. It's definitely a case by case basis. Consider it a different experience.
